It's going to be a challenge for future research. The main issue is in the past, when the long form was mandatory. We were fairly confident that we were getting a representative sample of the population and for these subgroups. Obviously, if individuals are refusing to complete the long form, and if that's not random, then we're going to have to try to account for that statistical bias, or any statistical biases that could come into it.
To be fair, that doesn't affect our results, and you certainly haven't implied that, but it will be a challenge going forward, yes.
